CLEANING- DEVICE.

Application filed July 22, 1921. Serial lilo. 486,752.

To all to 710m it may concern Be it known that 1, CHARLES W. Pu'rr, acitizen of the United States, residing at Jerome, in thecounty oflavapai and citate of Arizona, have invented a new and useful CleaningDevice, of which the following is a specification.

This invention relates to a mixing device such as used in preparingbeverages at soda fountains and the like, and to a means for use inconnection therewith whereby the mixing device can be quickly andthoroughly cleaned after each mixing operation.

l leretofore it has been the practice to use a rotating spindle with asmall disk-like terminal which has been rotated at a high speedwithin acontainer holding the beverage. No means has been provided for cleaningthis device after each successive op eration and, consequently, there ihas been danger of contamination of the prepared beverages.

Une of the objects of the present invention is to provide a cleaningmeans set up permanently in a fixed position relative to the mixingdevice whereby, after each successive operation of the mixing device itcan be lowered into the cleaner, such action resulting in the operationof 'avalve whereby a cleansing fluid is directed onto the stem of themixer and is drained therefrom.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

The accompanying drawing represents the preferred form of the inventionpartly i elevation and partly in section showing the mixing device inposition within the cleaning apparatus.

Referring to the drawing by characters of reference 1 designatesthe baseofthe ing device, the same being attached to a counter C or othersupporting structure. Extending upwardly from this base is a tubularhousing 2 having an annular flange or collar 8 at its upper end. A guidestem at projects upwardly from the base and is concentric with thehousing and slidably niounted within the housing is a cylindrical stem 5having an elongated recess 6 into which the stem l projects. A coiledspring 7 is arranged within the stem 5 and around the stem/t and bearsat one end against the base 1 and at its other end against the upperwall of the recess 6. This spring thus serves to hold the stem 5normally raised within the housing 2. In order to hold the stem 5 in itslowermost position with the spring 7 under compression, a latch 8pivot-ally connected to the upper portion of the stem 5 and isadapted,when said stem is thrust downwardly, to engage the collar 3 as shown inthe drawing.

.l'in elongated head 9 is provided at the upper end of the stem andforms a hand rest and extending from this head is a projecting portion10 to which is secured the housing 11 of an electric motor. A. spindle12 extends downwardly from the housing and is adapted to be driven bythe motor, this spindle being provided at lower end with a small disk13.

The structure thus far described is that used foij mixing beveragesplaced in glasses or other containers, thespindle 12 being inserteddownwardly into the beverage and then rotatedby the motor. For thepurpose of cleaning the spindle after it has been raised from the mixedbeverage. there is mounted on the supporting structure U at a properpoint, a housing 14: divided by a transverse partition 15 into a lowerwater compartment 16 and an upper cleaning compartment 17. Supportedwithin the cleaning compartment is an inner casing 18 having a pluralityof apertures communicating with the space therearcund and thereunder andextending from the bottom of this inner casing is a drain pipe 19. Aninlet opening 20 is formed in the partition 15 and is normally closed bya valve 21 having a stem 22 extending downwardly therefrom into aremovable screw plug 28. A spring 2% serves to holdthis valve normallyupon its. seat so as to close the opening 20. A stem 25 projects fromthe valve 21 through the opening 20 and through an opening in the bottomof the inner casing 18 where it will be contacted by the disk 13 whenlowered into the inner casing.

The inner casing 18 is adapted to be inserted downwardly into thehousing 14:

through a threaded opening :26 inthe top of the housing and screwed intothis open ing is a retaining ring 27 havlng a clownwardly taperedopening 28 provided with a rubber gasket 29 or the like constituting alining.

Normally the valve 21 is shut. After the soindle 12 has been used formixing a beverage the stem 5 can be rotated so as to position thespindle above the opening in the top of the housing 14. The spindle canthen be moved downwardly so as to cause the lower portion of the motorhousing 11 to engage the gasket 29 and close the top of the housing. Atthe same time the latch 8 will engage collar 3 and hold the parts intheir lowered positions and the disk 13 will come against the stem 25and open valve 21. This water supplied to the compartment 16 through aninlet pipe will flow upwardly into the space between the housing 14 andthe inner casing 18 and will be delivered in small ets through theopenings 31 in the inner casing and thus thoroughly clean the spindle 12and the disk 13. The Water will drain outwardly through the pipe 19 andthe cleaning operation will continue as long as the parts are held intheir lowered positions. By releasing the latch 8 the spring 7 willauton'iatically raise stem 5 and motor casing 11 whereupon the valve 21will automatically close.

lVhat is claimed is v 1.. The combination with a motor having .a taperedneck of a cleaning device for cleaning an article rotated by said motorcomprising an imperforate housing having a closed lower end and an openupper end, a retaining ring removably mounted in the open end of saidhousing with its inner face beveled to form a seat for said motor neck,a perforated inner casing mounted in said housing beneath said retainingring and spaced from the side walls of the housing, and means operableby contact with the article being cleaned in the casing to admit fluidunder pressure into the space between the housing and the casing wherebyit is forced out in jets through the perforations in the casing againstthe article to be cleaned.

2. A cleaning device of the class described comprising an imperforatehousing having an open upper end equipped with a retaining ring, aperforated casing mounted in the housing beneath said ring, said housinghaving a transverse partition near its lower end with an opening in saidpartition, a spring pressed valve to normally close the opening in thepartition and having a stem extending through said opening and looselythrough the bottom of the casing to position it for engagement by anarticle to be cleaned to open the valveagainst the tension of itsspring, the bottom of said housing having a fluid inlet opening there.through beneath said partition, and a drain pipe opening through thebottom of the casing.

In testimony that I claim the foregoing as my own,I have hereto affixedmy signature in the presence of two witnesses.
